.is a specification.

This invention relates to that kind 4of apparatus for Winding bands and the like onto cables, rods, or tubes, heretofore employed,

I in which the bobbins carrying the bands, &c.,

to` be Wound onto the cable are rotatably arranged' in fixed bearings, While the cable or other object to becovered is rotated` and is. at the same time advanced longitudinally. This arrangement has the advantage that the bandsfac., can be led through a liquid material for impregnating the same and renf dering themadhesive. y

y he present lnvention relates to means ,employed in connection with such apparatus vWhere v the rotation of the cable, 86h., and

the longitudinal acl-Vance thereof are effected simultaneously Without requiring any further auxiliary device. YFor this purpose there is provided a' frame rotatableround the longitudinal axis of the cable or other object, Whichfranie carries rollers that canbe pressed toward each other and are thereby made to 'grip the cable between them so as to eiiect its' rotation round its longitudinal axis as Athey revolve with the frame, While wormgearing, inJ connection with the rollers and engagedwith a `stationary Worm-Wheel or toothedi Wheel arranged outside the revolving fraine, effects the rotation of the rollers' on their axes, whereby the` cable, &c., to be covered has an advancingmotion imparted to it si nultaneously with the rotary motion impart dby the frame. y

In order to afford abetter grip on the cable, endless bands of suitable material are stretched over each air of rollers, which bands are formed wit longitudinal grooves that iit accurately round the circumference of the cable. In place of the endless bands the rollers maybe provided with grooved 'peripheries I shall describe the said invention 'with reference to the accompanying drawings, `in

' to 11 show dia longitudinal section, a sectional plan, vandv i cross-section on line A B, Fig.4 ,1, of one ar- 5 g rangement. Fig.l 4 shows a partial longitudinal section of a modiiied construction; Fig. 5 an end viev7 ofthe actuatin gear, While Figs. 6 and 7 show views of o't` er arrangements of. the actuating-gear.

motion`of the cable, &c

The frame a, Figs. 1, 2, and 3, has 'at its ends .tubular journals b and. c, rotatably mountedinfixedbearings d, so that the entire ammatic views of different arrangements or effecting the longitudinal,

frame can be rotated by means of the toothedI wheel e, suitably driven. In the framea are mounted the rollers gand g', se g to rotate andv move forward the cable- In or` der to insure a reliable grip of the rollers upon endless 'grooved chain may vbe em loyed. .The rollers g are rotatably mounte uponaxes y', that are carried by the frame a. Each the cable which is to` be covered by the bands of the 'two rollersghas` a lateral rectangular x l projection on which is fitted a spiral'wheel 7c,- vWhich is en aged with a stationary annular spiral gearl ,suitably` supported outside the framea, 7

The axes j of the through the frame a, but are carried in longitudinal slots in the frames m, which are pivotally mounted onthe axes j'.

n, to which are xed screws having nu s, by

rollers g do 'not extend turning which the rollers g can be shifted so..

as to stretch the bands For enabling theollersg to belpressedl.

toward each other screws o' are provided on l 9o i To the axes j are connected looped reces the frame@ by means of nuts on which bearing on the frames m the pressure exercised by the roller uponfther cable can be regulated.

On rotatlng the frame a, together with the above-'described arts carried thereby, `by

means of the toot edwheel e, the cable f Will v'be carried'round with it. As* the .worm- `Wheels lc'are engaged With-the xed annular Which- Figures 1, 2, and 3 show, respectively, al tated :upon their axes, whereby' the cable flWorm lthe rollers g are at the same time ro# 1o 5 wherein the Worm-Wheels io` xviii at the same time be advanced longitudirollers'i alone are employed, While Fig. 1.1

nelly,

in the arrangementshown in Figs. 4 and 5 the Woriwwheeis it' are engaged Witi spirallyformed teeth on a ring p, fixed to the face of one of the bearings d.

worm and worm-Wheel orear is employed, are engaged with Worms g, rotatably mounted on the frame a and rotated by. toothed pinions r, gearing i with a fixed toothed ring s.

In lche arrangement shown 1n Fig. 7 the in the arrangement shown in Fig. 6 a

l l l 1 i l shows an arrangement of two 0rrooved rollers t in combination with one endless band h.

I claim- In an apparatus for covering cables, rods, tubes and the like, the combination witha rotatable frame, of rollers adapted to revolve therewith and to rotate around their inditoothed pinion r, 'fixed to the Worm q, is enrotating the cable and simultaneously yadgagod with an internally-toothed ring s.

Fig. 8 shows f liagrannnatically the arrangement of a double set oi' endless bands h, passing over corresponding sets of grippingp rollers.

Fig. 9 shoii's an arrangement. in which one endless band of eaoli set isreplaeed by a sini hgreeted roller 1E. in 'the arrangement at Fig. l0 grooved vidual axes, endless bands placed over said rollers and formed with grooves adapted to grip the article to be covered, and means arranged independently of said frame, ada teil to rotate the said rollers while revo ving with the frame around their axes, thereby vancing the same.

ln testimony whereof I have hereunto set my h and 1n presence of two subscribing wit- HQSSES.
